Priming the Epileptic Brain: tVNS to Improve Efficacy of add-on AED in Patients With Focal Epilepsy...

Focal Epilepsy

The most prevalent neurological disorder with also immense burden of disease, epilepsy, is in over 30 percent of patients difficult to treat. The ideal treatment regime would give complete control of disease in an early stage, not only for patient well-being, but also to prevent the onset of persistent pathologic epileptic networks in the brain. The first step in treatment is the trial, and error, of multiple anti-epileptic drugs (AEDs), while invasive brain stimulation (BS) techniques with network modulating properties are saved as a last resort. The investigators hypothesize that pharmacotherapeutic treatment of epilepsy can be more successful after "priming" (preparing) the brain using BS as a short-term neuromodulation treatment. The limitation of testing this hypothesis is the invasive aspect of the most used classic vagal nerve stimulation (VNS) treatment for epilepsy, but the recent development of transcutaneous vagal nerve stimulation (tVNS) offered a possibility to combine chemical and electrical modulation in an earlier stage of disease, which is not tested before. The investigators want to determine the priming effect on the epileptic brain of tVNS, to make it more susceptible to add-on treatment with Brivaracetam (BRV), an AED. In addition, the investigators aim to visualize these changes in the brain because of priming, possibly altered network-organisation.

Cathodal Transcranial Direct Current Stimulation in Patients With Drug-resistant Focal Epilepsy...

Drug Resistant Epilepsy

The basis of this project is the application of cathodal tDCS in patients with drug-resistant focal epilepsy including patients whose seizures persist after epilepsy surgery, who rejected epilepsy surgery, and/or who are not suitable for surgery. For this purpose, 5-day consecutive cathodal electrical stimulation sessions will be used with personalized electrode montage according to the patient's seizure focus. In this context, the changes in seizures frequency and epileptic discharges will be examined for the first week and 12th week after the tDCS sessions through the seizure diary of the patients and the electroencephalogram (EEG) recordings to be taken. In addition, changes in cognitive functions, mood, and quality of life will be examined in patients after the intervention.

TMS Combined With EEG/EMG as a Biomarker Predicting Antiepileptic Drug Response

Focal Epilepsy

Ιn the present study (BIOEPI), the following three hypotheses will be investigated: The proposed TMS-EEG / EMG protocol (which includes software for calculating the cerebral cortex stimulation threshold) in combination with advanced signal analysis and data mining methods will allow the detection of the effect of antiepileptic drugs (AED) with different mechanisms of action (lacosamide & brivaracetam) in the Central Nervous System under healthy and pathological conditions (Epilepsy). AED-induced changes in selected TMS-EEG / EMG features predict the clinical response of individual epileptic patients to AED. AED-induced changes in selected TMS-EEG / EMG features may predict cognitive side effects.

MELD as an Adjunct for SEEG Trajectories

EpilepsyEpilepsy3 more

Epilepsy is a disorder of the brain which is associated with disabling seizures and affects 100,000 people under 25. Many children with epilepsy also have a learning disability or problems with development. Although better outcomes occur in children who are successfully treated early for their epilepsy, 25% continue to have seizures despite best medical treatment. One potential treatment is a neurosurgical operation to remove parts of the brain that generate seizures. A proportion of these children have electrodes inserted into their brains as part of their clinical assessment, termed stereoelectroencephalography (SEEG), to help localise these regions. Subsequent surgery is not always successful - up to 40% of children will have ongoing seizures 5 years after surgery. The planning of where to place SEEG electrodes relies on experts (neurologists, neurophysiologists and neurosurgeons) using information from multiple sources, which are used to generate hypotheses about where the seizures are coming from. The main components are the patient's magnetic resonance imaging (MRI) scan and video-electroencephalography (EEG) recordings during seizures. Using this information, between 5-18 electrodes are implanted and the recordings continue for 5-15 days in hospital. A focus is identified in about 75% of cases which means that the focus is sometimes missed. This prospective single arm pilot study aims to assess a new automated lesion detection algorithm, MELD, designed to identify focal cortical dysplasias (the most common pathology associated with focal epilepsy in children) on otherwise 'normal' MRI scans. The investigators will assess whether MELD can be used to improve the targeting of abnormalities in children undergoing SEEG recording at Great Ormond Street Hospital

Diffusion MRI Methods to Minimize Postoperative Deficits in Pediatric Epilepsy Surgery

Focal Epilepsy

This project will test the accuracy of a novel diffusion-weighted magnetic resonance imaging (DWMRI) approach using a deep convolutional neural network (DCNN) to predict an optimal resection margin for pediatric epilepsy surgery objectively. Its primary goal is to minimize surgical risk probability (i.e., functional deficit) and maximize surgical benefit probability (i.e., seizure freedom) by precisely localizing eloquent white matter pathways in children and adolescents with drug-resistant focal epilepsy. This new imaging approach, which will acquire a DWMRI scan before pediatric epilepsy surgery in about 10 minutes without contrast administration (and also without sedation even in young children), can be readily applied to improve preoperative benefit-risk evaluation for pediatric epilepsy surgery in the future. The investigators will also study how the advanced DWMRI-DCNN connectome approach can detect complex signs of brain neuronal reorganization that help improve neurological and cognitive outcomes following pediatric epilepsy surgery. This new imaging approach could benefit targeted interventions in the future to minimize neurocognitive deficits in affected children. All enrolled subjects will undergo advanced brain MRI and neurocognitive evaluation to achieve these goals. The findings of this project will not guide any clinical decision-making or clinical intervention until the studied approach is thoroughly validated.
